The result set that I wish to search will look like this:

Code:

Jul  3 23:12:14 mf04 postfix-mxmf/qmgr[6250]: CCB2825AE1C: from=<test@test.com>, size=2546, nrcpt=2 (queue active) 
Jul  3 23:12:14 mf04 postfix-mxmf/smtp[31012]: CCB2825AE1C: to=<user1@domain.com>, relay=some.server.address[192.168.30.201]:25, delay=8.2, delays=8.1/0.01/0/0.02, dsn=2.0.0, status=sent (250 low[1484]) 
Jul  3 23:12:14 mf04 postfix-mxmf/smtp[31012]: CCB2825AE1C: to=<user2@domain.com>, orig_to=<user1@domain.com>, relay=some.server.address[192.168.30.201]:25, delay=8.2, delays=8.1/0.01/0/0.02, dsn=2.0.0, status=sent (250 low[1484]) 
Jul  3 23:12:14 mf04 postfix-mxmf/qmgr[6250]: CCB2825AE1C: removed

Keep in mind that these results are stored in a variable called "results", and the IFS variable has been set to an empty string so that, when echo'ed, the above results will display with line breaks intact.

I want to filter out the lines with "postfix-mxmf/smtp" and just process those. For each line, I want to grab the email address and the "low[somenumber]". Both of these I can do with regexes, that's no problem. It's processing the output line by line that I'm having trouble with.

The end result is that, for each "postfix-mxmf/smtp" line, I grep another logfile for the email address and "low[somenumber]" and return a line that shows that the message was delivered, like so:

Code:

Jul  3 23:11:39 drd00 bingo[22660]: rfc2821: low[1484]: to=<user1@domain.com>, delay=0, status=sent 
Jul  3 23:11:39 drd00 bingo[22660]: rfc2821: low[1484]: to=<user2@domain.com>, delay=0, status=sent

Thanks for the help!

cmannotifyd

cmannotifyd(8)						     CMAN Notification Daemon						    cmannotifyd(8)

NAME

       cmannotifyd - CMAN Notification Daemon

SYNOPSIS

       cmannotifyd [-f] [-d]

DESCRIPTION

       The cmannotifyd daemon talks to CMAN and provides a mechanism to notify external entities about cluster changes.

       CMAN dispatches 3 kind of notifications:

       - CMAN_REASON_TRY_SHUTDOWN when cman requests to all clients if it is allowed to shutdown.

       - CMAN_REASON_STATECHANGE when cman detects a node joining or leaving the cluster.

       - CMAN_REASON_CONFIG_UPDATE when a configuration change event has been detected/requested.

       These notifications are then dispatched to the shell script cman_notify in the environment variable CMAN_NOTIFICATION.

       cman_notify will then execute all the scripts in the configured notification directory (default: /etc/cluster/cman-notify.d) passing a very
       minimal set of envvars including, of course, the CMAN_NOTIFICATION= type.  The execution order is set by the filename as shown by "LC_ALL=C
       ls -las".

       cmannotifyd logs are stored in the default log file (/var/log/cluster/cmannotifyd.log).

       cman_notify  logs are stored in the default log file (/var/log/cluster/cman_notify.log). By default the output from the scripts executed by
       cman_notify is redirected to /dev/null.	Users can either set CMAN_NOTIFICATION_DEBUG=1 in their environment or set proper debug configura-
       tion in cluster.conf to redirect scripts output to the cman_notify log file.

NOTES

       cmannotifyd does not block on cman_notify nor check the exit status of the script.

       Notifications are dispatched in the same order as they arrive, one by one.

       CMAN_REASON_TRY_SHUTDOWN  is  passed  to  scripts  for information only, they can not influence cman's decsion about whether or not to shut
       down.

       CMAN_REASON_STATECHANGE also implies CMAN_NOTIFICATION_QUORUM exported in the environment. CMAN_NOTIFICATION_QUORUM will be set to 1  (when
       the node is part of a quorate cluster) or 0 (otherwise).

       A template for cman_notify scripts can be found in the doc/ directory.

OPTIONS

       -f     Run in the foreground (do not fork / daemonize).

       -d     Enable debug output.
